Abstract: A robotic floor cleaning device that features a controlled liquid releasing mechanism. A rotatable cylinder with at least one aperture for storing a limited quantity of liquid is connected to a non-propelling wheel of the robotic floor cleaning device. There is a passage below the cylinder and between the cylinder and a drainage mechanism. The cylinder is within or adjacent to a liquid reservoir. Each time an aperture is exposed to the liquid within the reservoir it fills with liquid. As the wheel turns the connected cylinder is rotated until the aperture is adjacent to the passage. The liquid in the aperture will flow through the passage and enter the drainage mechanism which disperses the liquid to the working surface. The release of liquid is halted when the connected wheel stops turning.
